Relationship between mobile phone use and multidimensional frailty: evidence from UK Biobank.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To investigate the longitudinal temporal relationships between weekly mobile phone call time and four dimensions of frailty. Methods: Data were derived from three instances (T1, T2, T3) of the UK Biobank. Frailty encompassed four dimensions: psychological, physical, social, and cognitive. Separate Random Intercept Cross-Lagged Panel Models (RI-CLPM) were constructed for each frailty dimension with weekly mobile phone call time, measured by self-reported weekly mobile phone call time standardized to baseline. Chi-square difference tests and the BIC were adopted for model comparisons. Results: This study included 5,533 participants aged 40-70 years. Unconstrained models outperformed constrained models for all dimensions ( Conclusion: This study examined prospective within-person associations between weekly mobile phone call time and frailty dimensions in a middle-aged and older adult sample (baseline age 40-70 years). After FDR correction for multiple testing, most cross-lagged associations were not statistically significant. Only two paths reached significance or marginal significance: social frailty T2 → weekly mobile phone call time T3 (β = 0.078,
